At asymmetric overloads on multi-pole types, the tripping characteristic will change. Ifa2-pole type TA35 is loaded at one pole only,the tripping current will be shifted by factor1.05. Ifa3-pole type TA35 is loaded at one pole only,the tripping current will be shifted by factor1.10. To meet the above tripping characteristic at asymmetric overloads on multi-pole types, the value of the rated current of the CBE has to be multiplied by the factor mentioned above. effectofambienttemperature The unit is calibrated for an ambient temperatureof+23 C. To determine the rated current for lower or higher ambient temperature, useacorrection factor from the table below.
